I have a Cobra 148GTL, as well as a Cobra148NWST, I plan on taking both in for minor repairs/peaking and tuning. At the same time, could I have weather channels added to these CB's? Would it be more economicalto just buy an SSB CB with weather channels already available. I have hard really good things about the 148GTL, but is the 148NWST much different, other than the NiteWatch feature, which I really like? What are the probs with the SoundTracker feature?
